Anil, Sunil, and Ravi run along a circular path of length $3\mathit{k}\mathit{m}$, starting from the same point at the same time, and going in the clockwise direction. If they run at speeds of $15\mathit{k}\mathit{m}/\mathit{h}\mathit{r},10\mathit{k}\mathit{m}/\mathit{h}\mathit{r}$, and $8\mathit{k}\mathit{m}/\mathit{h}\mathit{r}$, respectively, how much distance in $\mathit{k}\mathit{m}$ will Ravi have run when Anil and Sunil meet again for the first time at the starting point?
